Abstract
This paper presents an experimental study, in several scenarios of energy consumption in a vapor compression refrigeration system when it operates using ON-OFF, linear and fuzzy logic control schemes. The proposed study scenarios pretend to emulate real operation conditions in refrigeration systems such as a disturbance produced by the door opening. In the test bench used in this study the ON-OFF, PID and fuzzy logic control strategies were implemented via Labview® and National Instruments® hardware. The system provides the energy consumption in each control strategy for a given set of conditions. In addition, the vapor temperature tuning is observed. The results reveal larger energy savings, near 25% , via linear control and fuzzy logic and a satisfactory tracking of the reference compared with ON-OFF. The results of this study can be used as support information when determining a control scheme for a large refrigeration system.
